*** Forecast - Our water temperature forecast
Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

Location & Local Information
Frissjön, a small lake in Jönköping County, typically follows the seasonal temperature patterns of southern Swedish inland waters. In winter the surface often hovers around 0–4 °C (32–39 °F) and may freeze over for periods, while spring warming brings temperatures to roughly 4–12 °C (39–54 °F). During summer, surface temperatures commonly reach about 15–22 °C (59–72 °F) on average, occasionally rising a few degrees in warm spells. In autumn the water cools back toward roughly 8–14 °C (46–57 °F). These figures are approximate and depend on weather, depth, and local inflows, so conditions at Frissjön can vary year to year.
Swimming in Frissjön is generally possible and permitted because Sweden’s public access traditions allow bathing in most natural waters, and there are no widespread prohibitions specific to the lake. Local shorelines or private properties may restrict access in places, and water quality can vary, so it is sensible to check municipal advisories if available. There are no guarantees of lifeguards or facilities; cold-water risks should be respected, especially outside the warmest months, and ice or thin ice in winter makes swimming hazardous and unsuitable without proper precautions.
